"Maybe the reliability is not as good as that of the fiber," Henkel said. "Maybe that's why it is not seen as an alternative because many people think in the long term, which is good. But it also takes a long time to implement something like a fiber. We are quick but we are not as future-proof. "

Financing is also a problem, Henkel said. "Even if you have a request for a small amount of money, I think it still takes a long time to actually commit people to give you the money to invest."
